Blender wiki manual (unofficial) updated: 20090129 in PDF format, is a simple PDF conversion of over 250 wiki pages, results in over 1300 pages easily viewable, printable, searchable.
NOTE: archive.org automatically generated other versions, but for DJVU and DJVUTXT versions but they used OCR, with too low resolution (72dpi), so both are unreadable, and just a waste of space, IMHO). Please use PDF only.
Original wiki content is under http://opencontent.org/opl.shtml license. I uploaded just because its original site (http://www.letworyinteractive.com) is down with no recover in sight, some user asked me to make this available somehow. Maybe it's a a good idea store them here in the future, i'll see.
NOTE: this pdf refers to a quite old version of Blender, you can find a newer 2.6x version here https://archive.org/details/BlenderWikiManualPdf20121019 and you will find newer versions too, later
